hi,

比如:
Cpu0 : 0.3%us, 60.7%sy, 2.7%ni, 35.7%id, 0.0%wa, 0.0%hi, 0.7%si, 0.0%st
Cpu1 : 0.0%us, 0.3%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st

us是use, sy是system,ni是niceness, 然后其他的是什么?找了半天都没找到。

呵呵,原来小马在啊? 哦,对了,上次你说的可以模拟嵌入式开发的模拟器叫什么?
我上次记录下来忘记放哪里了。想试试看。

也不能说是全国产吧,只是主导者是清华的chen yu大侠,好像barry老师也在搞?
skyeye的弱点是可读性强的文档几乎全无,user man也几乎等于没有,新手写个conf文件要晕死的

呵呵,纠结中,到底选哪个比较好,想学学嵌入式,提高一下自己。呵呵

如果是学生,有得是时间折腾,都可以尝试一下。

如果工作了,那么建议还是去买块arm9的开发板,实物总要比模拟器好。

ARM9 的板子是不是大概800多块,还要有J-tag啊什么的。。。。很多东西似乎要一应俱全啊。前期投入蛮大的,是不是还的先把C学学透彻? 还是只要看得懂文档,然后会交叉编译就可以啊?

其实搞个arm板调试跟弄台x86也没什么区别吧,CPU相关的就几个文件,MIPS、powerpc等也不比arm用的少,arm只是在消费电子方面独占鳌头。
以前家里的80286电脑15块钱卖给了收废品的,现在想想,说不定还是个搞嵌入式的好板子,哈哈
